Hispanic type names

My first post, so Hello!

I'm 39 weeks pregnant, and still have no idea what to call our boy! Assuming of course that it will be a boy and the sonographer didn't make a mistake...!

Anyway - looking for some inspiration for names that work well in English and Spanish. OH is quite taken by the name FelixNathaniel, and I like the idea of Gabriel as a first name - although I'm well aware it might get shortened to Gay in the playground (character building, no?). We also have Luca on the list, and Caspar. But I don't know!

I really like the nickname Gabi for Gabriel... and honestly, I know guys named Gaylen who've survived, and my aunt's name is Gaye so I don't think it'd the end of the world to have 'gay in a name.
I love Caspar myself! FelixNathaniel is great, too.
